Solo dev. 9+ years in mobile and web, and I've been writing code for the web since 2012. React Native has been my main stack for the last 6 years - TypeScript, JavaScript, the usual. I picked up Flutter in 2020 and now I split my time between the two. Flutter gives me fewer headaches, but I'm not religious about it: if you already have a codebase, I work in whatever it's written in. If you're starting from zero, I'll tell you which one actually fits your case instead of pushing my favourite. Before mobile I was a front-end developer. Android from 2015, and a year later I bought my first MacBook to write native iOS. Objective-C. I remember it. How I work: I take projects from idea to store release, and I stick around after. Most of my clients come back with the next thing. I write tests and set up CI/CD, so shipping isn't a manual ritual every time. I ask questions early instead of guessing and rebuilding later. If something in your spec is a bad idea, I'll say so before I build it. Mobile: React Native, TypeScript Flutter, Dart Swift, Kotlin - I can write native components when RN or Flutter doesn't have what you need FlutterFlow (since 2023) RevenueCat, branch io, Sentry GitHub Actions, Fastlane, CircleCI for CI/CD Tests: Jest, Mocha, Jasmine Web: Next.js, Node.js, React.js, Redux, GraphQL AWS, DigitalOcean, Heroku, Retool Supabase Firebase, the whole set: Firestore, Realtime Database, Cloud Functions, Auth, Cloud Messaging, Remote Config, Hosting, Cloud Storage, ML, Dynamic Links Web3: Blockchain development, DApps, DeFi, LayerZero Crypto wallet integrations (MetaMask, AlphaWallet), Tokenscript Token launches Casino game mechanics (spinner, coinflip, lottery, splash) ChatGPT / OpenAI and other AI integrations Infrastructure & keeping sites alive: This is the other half of what I do, and it's usually urgent when someone contacts me about it: DDoS protection. Getting a site back up when it's under attack, then making sure it stays up — Cloudflare, WAF rules, rate limiting, hardening the origin so it isn't reachable directly. Highload fixes on PHP projects. Most often WordPress + WooCommerce shops that die under real traffic. Slow queries, missing indexes, no caching layer, cron running wild, twenty plugins doing the same thing. I find what's actually eating the server instead of just throwing more RAM at it. Monitoring for small infrastructure. Uptime, alerts, dashboards — so you hear about a problem from me, not from your customers. This works as an ongoing monthly arrangement; message me and we'll size it to what you have. If you're not sure whether your project fits, just send me a message and I'll give you an honest answer.

I build cross-platform applications across games, mobile, and desktop, with a focus on performance, stability, and production-ready architecture. In game development, I work with Unity and Unreal Engine to create interactive experiences, real-time systems, and simulation-driven applications, including gameplay mechanics, UI systems, and performance optimization. My work often involves handling real-time rendering, physics, and scalable game logic for both standalone and connected environments. For mobile, I develop applications using Swift and Kotlin for native performance, and React Native and Flutter for cross-platform delivery, ensuring consistent UX across iOS and Android. I’ve built apps ranging from consumer products to data-driven tools, with strong attention to responsiveness and maintainability. On the desktop side, I use C++ and Electron to develop high-performance applications and custom tools, including system-level utilities and UI-driven software. I focus on efficient resource management, clean architecture, and seamless integration with external services and APIs. My approach is to deliver reliable, scalable solutions that perform well under real-world conditions, whether it’s a game, a mobile app, or a desktop system.
